E Series Dump Pump

The Muncie E and EH Series dump pumps are designed to meet the needs of the dump trucking industry. Muncie dump pumps are available in both direct and remote mount configurations; standard or extra-large port sizes; two or three line plumbing; and air, cable, or lever shift.

  • Three piece, cast iron construction: Heavy duty, rebuildable
  • Roller bearing design: Long product life
  • Pressure-balanced wear plates: High efficiency
  • Larger ports (EH models): Fast cycle times
  • Remote and direct mount models: Versatility
  • 2 or 3 line options: Versatility

3-Line Dump Pump System

Many dump bodies function quite adequately with a 2-line design. However, a 3-line system includes a separate line to return hydraulic oil from the cylinder directly to the reservoir instead of forcing its way back through the inlet line.

The separate line is recommended when used for road building or stockpiling material because the 3-line pump allows faster down cycles, provides an easier method of filtering the hydraulic oil, and ultimately runs cooler.
